I'm not an expert, but from my understanding if arrest warrant comes out, the boys in blue will come n drag u to the court n give u judgement if admit guilt, but if u wanna fight it out, they probably set bail (it's court discretion), and if the court believe u a high risk, dey will ask for Ur passport, and worse case scenario u be in lokap till Ur court dates or judgement

But I've never heard anyone reach that stage for just speeding fine, but there's always a first time I guess
